The men's Power Stretch Pant by Marmot is a pant designed for outdoor aerobic activities with its high impact warmth, ample breathability and incredible stretch. The durable nylon outer layer is wind- and abrasion-resistant; the soft inner layer pulls moisture away from your skin keeping you dry, warm and comfortable. Cold weather running, ice climbing, hiking, and climbing all require a pant that can allow total freedom of movement without weight, and the Power Stretch pants will provide you the ability to be in the outdoors with comfort and mobility.

These pants are very warm. They work best for extremely low temps and wind. I use them as an outer layer for winter cycling, trail running, and climbing. They also work well as a base layer in cold mountain conditions. The only improvement I would recommend is incorporating ankle zippers for easier on/off. Other than that these are great pants that I think are a staple item for endurance athletes.
